Telephone number extension (Help Needed)

Hello everyone,

I am new to the FHIR messages. Does any one know how to include telephone number extension in the FHIR patient resource? Any examples that i can take a look?

Based on my research I find acontactPoint extension, but it is just regular extension format. And I couldn’t find any example on how people use it in the message. I wonder dose anyone do the same thing before? Or maybe know how to do it. so that I can take a look at it?

Thanks in advance for your help.

Two choices:

“telecom”:{
“system”:“phone”,
“value”:"+1-(123)-456-7890 ext 15"
}

or

“telecom”:{
“extension”:[{
“url”: “http://hl7.org/fhir/StructureDefinition/contactpoint-extension”,
“valueString”:“15”
}],
“system”:“phone”,
“value”:"+1-(123)-456-7890"
}

The first of those will probably be more typical. The latter is generally used along with the area, country and local extensions to send the whole thing in parts. And when you do that, you should send the combined phone number in the value element too. (In fact, I probably should have included the extension in the value in my second example.)

Thank you Lloyd for your kindness help!
